The end of Windows XP support

According to the official announcement of Microsoft, the support of Windows XP will end on April 8th, 2014. It has been used widely for a dozen years. It is high time to make plans for upgrades. The statistics show that more than half of the computers are already using Windows 7. Presumably this will be one of the more serious platforms where upgrades are concerned. Switching to Mac OS X or Linux is definitely also considered.
